@bear78-- Yes, I took a course on interpersonal skills, communication and conflict resolution. If you're concentrating on conflict resolution, the most important things are being impartial, sympathizing with the parties to conflict and trying to find a middle ground.
I don't think it's a problem to put what you learn into practice. It might seem difficult at first, but after a few tries, it does become easier.
Usually though, if the conflict is an office conflict, it might be better to have someone from the outside to intervene and negotiate between the parties. Because it's difficult for people who work at the same place to remain impartial. People tend to take sides but resolving conflict requires that one does not do that. It's important to be objective and understand the grievances of both sides.
